Heat Energy and Heat
Transfer
Heat is a form of energy in
transition and it flows from one system to another, without transfer of mass,
whenever there is a temperature difference between the systems. The process of
heat transfer means the exchange in internal energy between the systems and in
almost every phase of scientific and engineering work processes, we encounter
the flow of heat energy.
Modes of Heat Transfer
The heat transfer processes
have been categorized into three basic modes: Conduction, Convection and
Radiation.
